REGISTERING DEVICE. v

Application filed April 22, 1912. Serial No. 692,393.

To all whom it may concern Be it known that I, 'WARO B. STORY, a citizen of the United States, residing in the borough of Brooklyn, county of Kings, city and State of New York, have invented a certain new and useful Registering Device, of

which the following is a specification.

. in a positive and easy manner. A further object is to produce a device which will insure positive action; to produce a device in which the gripper will have a minimum amount of movement, and to produce a device in which the sheets will be properly gaged before they are fed by the forwarding roller.

These and further objects will appear from the following specification and accom panying drawings, considered together or separately:

In the drawings, Figure 1 is a plan view, with the center broken away, of an apparatus embodying-my invention.

Fig. 2 is a detail of the same, with the clro rollers and the" gages and supporting sha s removed in order to show the details ofthe front and rear tables.

-Fig. 3 is a sectional view on the line 3-3 of Fig. 1.

Fig. 4 is a sectional view on the line 44l of Fig. '1; and

Figs. 5 and 6 are detail views of the gage.

The device illustrated comprises a frame 1, 1. The taking cylinder 2, and the type cylinder 3 are of the usual construction, ex-

cept as to certain details of the taking cylinder relating to the gripperand stop. I The front table-4 is carried upon'a support 4?, connected to the frame. The rear table 5 is carried upon a support 5 also connected to the frame. These tables are for the purpose of supporting the sheet when it is being fed tothe grippers. The forwardingroller 6 lies between the front and rear tables, and below the same. The drop roller 7 is above the forwarding roller. In the embodiment chosen for illustration, the forwarding roller is a continuous roller, best shown in Fig. 1.

Specification of Letters Patent.

Patented Aug. it, 1917.

The drop roller is formed of a number of rollers or wheels, best shown in Fig. 1. It will be understood that as many of these drop rollers are employed as is necessary to properly hold the sheet against the forwardinggoller and feed the sameforward.

he gripper 8 is carried by the taking cylinder 2. This gripper is in the form of a plurality of arms, best'shown in Figs. 1 and 4, so that the front edge of the sheet will be gripped. The stop 9, shown in the embodiment of at; invention illustrated, is in a plurality of pieces, and is adapted to be engaged by the front edge of the sheet. The stop is best shown in Figs. 1 and 4. The gage 10 is adapted to be lowered to the plane of the rear table 5, or to a slightly lower plane when in operative position, so that the sheet will be fed to it, and then, after the sheet is in engagement with the gage, the gage will be raised and the sheet will be free to be fed there is a clear space between the two rollers. The free end of the gage 10 is adapted to rest upon the rear table at this time,

'or to be slightly below the same, as will be described, so thatthe sheet may be advanced by hand, or by feeding devices, to a position with its front edge in. contact with the gage.

I The sheet, after being gaged, is fed to the taking cylinder and grippers by means of being brought into contact with the sheet and pressing it against the latter so that it is fed by frictional engagement therewith. At this moment, the gage is raised so as tov allow the sheet to be fed to the taking cylinder.

I provide mechanism for starting the sheet from rest to normal speed, or to the peripheral speed of the taking cylinder, or slightly faster than the peripheral speed of the same. gradually accelerate the speed from nothing up to the maximum. This mechamsm is as follows: The forwarding roller is supported upon, and is turned by, a shaft 11. This shaftcarries a-pinion 12 (see Fig. l.) A

the drop and forwarding rollers, the former .This mechanism is adapted to-105 pin 18. The pin is adapted to engage in one or another of the slots. The pin successively engages with the slots. as the gear 16 is rotated. The gear 16 also carries a segmental wheel 19. This wheel has a segment cut out, as best shown in Fig. 3, so that the slot-wheel may be turned when the pin engages with one of the slots. When the pin passes out of engagement with a slot, then the unmutilated portion of the segmental wheel will engage with the notched periphery of the slot-wheel. This mechanism produces a form of Geneva stop gear, th e principles of which are well un- I .derstood. A gear 20 meshes with the gear 16. This gear iscarried upon a shaft 21. The shaft 21 extends across the machine, from one'side member of the frame to the other. A gear 22 meshes with the gear 20.

. The gear 22 is supported upon a shaft 23, which also supports the taking cylinder 2.

The shaft 23 is rotated by means ofa gear '24.

From the foregoing description, it is apparent that u on the gear 24 being rotated, 1n the embod1ment chosen for illustration, in the counter-clockwise direction, the gear 22 will rotate the gear 20, and the gear 20 will rotate the gear 16. The pin 18 will, during every revolution of the gear 16, engage one of the slots of the slot-wheel, and rotate the latter a quarter revolution. During the period of time in which the pin is not in engagement with the slot, the segmental wheel will engage with the notched periphery of the slot-wheel, and lock the same against movement. The rotation of the slot-wheel will rotate the gear 13, and this gear 13 will rotate the gear 12.. The gear 13 is shown as very much'larger than the "ear 12, so that a quarter revolution of the ormer will rotate the gear 12 a number of times. The proportions are such that the gear 12 will be rotated, and the forwarding roller will be rotated a sufficient number of times so as to feed thesheet positively to the gripper. It should be understood that the proportions of the parts may be varied in accordance with the particular situation. The device just described locks the forwarding roller against movement at certain times, and then it rotates it, with a gradually accelerating speed up to maxiaaaaaea sheet now begins to be retarded but before its speed is lowered to that of the normal or peripheral speed of the cylinder the leading edge of the sheet will be crowded against the stops on the cylinder and be seized by the gripper. If desired the parts may be so proportioned that the leading edge of the sheet will be delivered 'to the stops on the cylinder before the sheet reaches its maximum speed but the speed of the sheet must always be at least as great as that of the periphery of the cylinder when the sheet is engaged by the grippers.

For the purpose of lifting the drop roller from contact with the forwarding roller so that a sheet may be fed against the gage, and also for the purpose of lifting the drop roller after the sheet has been fed into contact with the stop, so that it will then be fed by engagement with the gripper, I provide the following mechanism: The shaft 21 carries a cam 25, best shown in Fig. 3. This cam is of circular'shape, with one side eccentric. A lever 26 carries a roller 27, which engages with the cam 25. A shaft 28 supports the lever 26, and is rotated thereby. The shaft 28 carries arms 29, the free ends of which support the rollers 7 (see Figs. 1 and 4) An arm 30, at one end of the shaft 28, extends upward, and is for the purpose of attachment of a spring, to be described, for depressing the roller 27 when permitted by the position of the cam 25. The proportion of the gears20, 16, 13 and 12 is such that the shaft 21 will make one complete revolution for each sheet that is bein fed, so that at the proper time the roller 2% will engage with the eccentric part of the cam 25, and will depress the drop roller by the mechanism described. Also. at the-proper time, the roller 27 will engage with the raised part of the cam 25, and will lift the drop roller 7.

For the purpose of lifting the gage 10 at the proper time to permit a sheet, which has been fed against it and is gripped by the forwarding and drop rollers, to be fed forward, .I provide the following mechanism: A shaft 31 extends across the frame, and carries one or more grippers, 10, upon it. This shaft has at one end an arm 32 (see Fig. 3). The free endof the arm 32 carries a roller 33. This roller 33 engages against a cam 34, said cam being carried upon the shaft 21. This cam, as shown, has a high part and a low part. Another arm 35, car' ried by the shaft 31, extends upward, substantially to the same height as the arm 30. A spring 36 connects the two arms. The gages are preferably supported upon the shaft 31, and are adjusted in position by means of set screws 37, so that their angle to the shaft and their position along the shaft 130 3 cessively engage the high and low parts of the cam 34. When it engages with the high part, the shaft 31 will be rotated, and the gage will be lifted above the sheet. When the roller engages the low part of the cam, the shaft will be'rotated in the opposite direction, and the gage will be pressed down upon the table. The spring 36 exerts stress to depress the gage 10 and the drop roller 7.

The details of the preferred form of gage are shown in .Figs. 5 and 6. Each gage comprises a spring arm 38. This arm has a notch 39 in its free extremity. A spring 40 is secured to the arm 38, and lies within the notch. .This spring is preferably a weak spring, and its purpose is to prevent the sheet from sticking to the gage as the latter is raised. When in normal position, and out of contact with the sheet, the spring 40 extends slightly below the free end of the gage.

The details of the gripper are as follows The gripper arms 8 are carried upon a shaft 41. This shaft is mounted in suitable bearings in the taking cylinder 2. Upon one end of the taking cylinder the shaft is connected to a bell-crank 42. One arm of the bell-crank carries a roller 43. This roller is adapted to engage fixed, and is supported upon the frame 1. The other arm of the bell-crank is connected to a rod 45. A spring 46 surrounds the rod.

One extremity of the spring engages with a stop 46 on the rod, and the other extremity engages with a bearing or guide 47, carried the taking cylinder. The expansion of the spring tends to draw the roller 43 toward the center of the taking cylinder and to depress the grippers 8. The depression of the grippers will draw them into contact with the taking cylinder, and will hold the front edge of the sheet in position. The 10- cation and shape of the cam 44 is such that engaging with the taking cylinder turning in the counterclockwise direction will, at a slight'angular distance in advance of the place where the gripper reaches the rear edge of the rear table 5, cause the roller 43 to engage with the cam. The cam is eccentric, on an increasing radius. Consequently, the roller 43 the cam will be moved away from the center of the taking cylinder. This will turn the shaft 41, and will raise the ers. The sheet at this moment will have been fed by the drop and forwarding rollers, '60

and will be moving at the same speed as the peripheral speed of the taking cylinder. The sheet will be fed against the stop 9, and when it is in contact with the same, or is crowded against it, the roller 43 will engage with a portion of the cam 44' of decreasing radius. Consequently, the shaft a cam 44. This cam is 41 will be turned inthe opposite direction,

and the gripper will be lowered, through the agency of the spring 46, into contact with the front edge of the sheet, and will hold the latter, and will feed the same forward by such contact. Y

The details of the stop 9 are as follows: A shaft 48, mounted in bearings in the taking cylinder, carries the blanket clamp 49. This shaft extends through one end of the cylinder, and has an arm 50 on the extremity. This arm engages with a rod 51... A spring of the spring engaging a stop 52 on the rod and a fixed bearing or guide 53, so that the expansion of the spring will tend to turn the shaft 48 and engage the blanket clamp Withthe taking cyllnder'. The blanket 54 has one edge engaged by the clamp, and the other end is wound around the blanket roller 55 in the usual manner.

In order to insure that the sheet will always be fed above the rear table 5, I provide the following devices: The forwarding roller 6 is provided with a number of peripheral grooves 56. The front edge of the rear table is provided withflexible fingers 57, which enter these grooves and are curved downward sufliciently so that the sheet, when fed along the surface of the front table, will ride up over these'fingers and will properly be brought against the gage. sure that the gage will be lowered so that there will be no possibility of the sheet slipping between it and the table, I provide 52 surrounds the rod, the extremities In order to in- .These apertures are of such a size-that the free edge ofeach gage can be lowered a short distance through the aperture. To allow the rear table to extend sufliciently over the taking cylinder to support the sheet, and at the same time to allowthe taking cylinder to turn with the grippers elevated, I provide slots 59 (see Fig. 2) in the rear edge of the rear table to allow these grippers to pass throug s For the purpose of supporting the shafts 21 and 17 a bracket 60 is provided, having suitable bearings thereon. For the purpose of holding the sheet down upon the rear table, and also down upon the forwarding roller, when the drop roller is not in contact with it, I provide suitable guides 61 (see Figs. land 4). These guides are supported upon the shafts 28 and 31 by suitable bearings.

From the foregoing description, it isapparent that the sheets may be registered against the gage 10 to accurate front register, at the proper moment, in relation to the position of the grippers; the drop rollers will descend in contact Wltll the forwarding rollers, and grip the sheet at the same moment, or slightly-after this. The gages will der them. The sheet will be started from rest gradually untilit reaches a speed equal to the peripheral peed of the taking cylinder. It will then be brought gently against the stops. If the speed of the feed rollers be slightly greater, the front end of the sheet will be crowded against the stop, so that there will be a perfect front registry. As the sheet is under perfect control when it is brought against the stop, and is held down upon the rear table by means of the guides 61, it is apparent that the grippers need not be elevated to any great extent, it being suflicient that the space between the grippers and the stops and the taking cylinder be just enough to allow the sheet to be fed into this space. It is apparent that as the grippers pass the paper line at the head of the sheet, the speed of the sheet is this moment being accelerated, and is faster than the peripheral speed of the taking cylinder.

It is apparent that no time need be lost between sheets for registering, as they may be fed to the gage, owing to the fact that the period of time in which the drop roller is out of contact with the forwarding roller is very eat in comparison with the period of time 1n which they are in contact, which is the period of time during which the sheet is being fed.

If desired, the speed of the forwarding roller may be so proportioned that the advance of the sheet is in excess of the normal travel during the same period of time, so

that the duration of time during which the sheets can be fed to the gage is amplified.

In accordance with the provisions of the patentstatutes, I have described the principle of my invention, together with the apparatus'which I now consider to represent the best embodiment thereof; but I desire to have it understood that the apparatus shown is merely illustrative and that the invention can be carried out in other ways.
